I'm interested in this thread too. I am having Kooks 1 7/8" LT catted headers put in my L99 soon (the parts are on order). I am going to try them with the stock exhaust and then decide if I want to go with a Magnaflow Street series or a Borla touring exhaust. I want to be careful not to introduce an annoying drone at highway speeds. I am going to have a tune when I get the headers put in (AFM will be shut off as part of the tune).

I don't want an overly loud exhaust, but I do want something that will add a bit of a throaty growl to my car. I'd like to be able to listen to music and talk when cruising. So, I'm interested in this thread too - I'm not sure if magnaflow street or Borla touring is the way to go.

Wow, you and I are on the same page when it comes to our cars. First Adams, then CAI and now this. I am leaning towards the Borla touring for the same reasons. I think I'll let you go first again
